At the end of the 20th century and beginning of the 21st century, Vietnamese literature witnessed unprecedented innovations in the aesthetic thinking of writers and the narrative structure of their works. One of the most interesting manifestations of this new movement was not merely the introduction of new aesthetic materials and factors, but the adoption and positive ＂reprocessing＂ of traditional factors---especially historical factors and folk narrative factors. Based on intertextual theory, we would like to address the strong penetration, reproduction, and transformation of some folk storytelling models and historical materials in Vietnamese literature since 1986. Two corresponding phenomena we examine are ＂historical rewriting＂ and ＂alternative fairy tales＂--as part of the whole process of incredulity towards grand narratives and postmodernism in the contemporary Vietnamese prose.

为了提高超精密数控机床旋转B轴的对刀精度和效率,基于3点坐标确定圆心的原理,提出了一种可量化的B旋转轴对刀方法。采用一种非接触式图像识别方式进行精确对刀,可避免对刀过程中金刚石刀具的破损,同时解决刀尖视场与机床坐标不一致的问题。利用Fresnel透镜模具加工实验验证了对刀精度,并通过激光显微镜检测沟槽里尖角的圆弧半径来确定对刀误差。实验结果表明:该可量化对刀方法的对刀误差为0.8μm,该误差在预先计算的理论误差1μm范围里。该对刀方法适用于超精密切削加工,且对刀的精度可以预测和控制。

In order to design the production with complex external shapes, a newmethod is put forward using non-uniform rational B-spline(NURBS)curves to unifythe description of complex curves composed of several segments with different degrees,and then these complex curves are used to construct NURBS skinning surface. Somekinds of skills are used to dispose the knot of NURBS curves and surfaces for practicalproblems. Finally, the method is verified by several complex examples.

A new approach is proposed to generate flexible featrure based models (FFBM), which can be modified dynamically. BRep/CSFg/FRg hybrid scheme is used to describe FFBM, in which BRep explicitly defines the model, CSFg (Constructive solid feature geometry) tree records the feature based modelling procedure and FRg (Feature relation graph) reflects different knids of relationship among features. Topological operators with local retrievability are designed to implement feature addition, which is traced by topological operation list (TOL) in detail. As a result, FFBM can be modified directly in the system database. related features' chain reactions and variable topologies are supported in design modification, after which the product information adhering on features will not be lost. Further, a feature can be modified as rapidly as it was added.

After undergoing wireframe modeling, surface modeling and solid modeling, a unified product model, which holds a variety of constraints in engineering, supports design process, and unifies the wire frame, surface modeling, and solid modeling,is a general tendency of modeling technology. A discussion is presented here on how tobuild a unified product model by using the complex method. The concept of complex inalgebraic topology is introduced into the model and a new B-REP representation of thenon-manifold model is given --Identification Edge Structure. Based on it, some basicoperators and high-level operators are built. The model has a rigorous mathematicalbasis, and is flexible and easy to extend, and holds the lamina face, lamina edge andlamina vertex. As a result, the variety of constraints in engineering, such as parametricconstraints, optimization methods, fuzzy constraints, artificial intelligent, etc., can beadded to the system. The model may form the kernel for the implementation of the nextgeneration CAD system --intelligent CAD system.

Since regular surface is defined by a mapping from 2-D parameter plane to 3-D space, trimming of NURBS surface is equivalent to changing a valid parameter region ofthe surface with the same mapping. In this paper, by presenting a rigid and comprehensi-ble definition of union, difference and intersection of two intersecting loops in the parame-ter region of NURBS surface, and by working out the corresponding algorithm, a rebui1d-ing algorithm of the valid parameter region of NURBS surface is obtained.
